I know two many people that are using a laptop as a desktop because of space considerations, and have had the battery degrade to less then 10 minutes of runtime, while the same model laptop where they have used the battery (actually used it as a laptop.) has 90 minutes or more of runtime. I am not sure if this is because of the differences between the lead/acid gel-cells used in a UPS compared to the lithium-ion batteries, or if it is the battery charge monitor gets confused by the short charge/discharge cycles. I do know that the lithium-ion battery charge can not be measured by voltage level like the lead-acid batteries can. Bye the time the voltage starts dropping, they are almost dead.
